Abstract: Účelem řešení je získání alkydových
pryskyřic, které poskytují nátěry vytvrzované
při mírnějších podmínkách na rozdíl
od nátěrů z olejových typů alkydů. Tyto
nátěry mají srovnatelné tvrdosti a jsou
pružnější po daleko delší dobu než je dosud
známo. Dosáhne se toho tím, že alkydové
pryskyřice jako modifikující složku
obsahují 2 až 15 % hmot. segmentů složených
z jednotek kyseliny akrylové nebo
methakrylové a jejich derivátů, zejména
esterů obsahujících ,1 až 8 uhlíkových
atomů v alkoholickém zbytku vázaných se

Abstract: 1519041 Glass-fibre-reinforced cementitious products PILKINGTON BROS Ltd 19 Dec 1975 [2 Jan 1975] 88/75 Heading C1H [Also in Divisions C3 and Dl] Cementitious products are reinforced with glass fibres which have been coated with a composition containing, as a protective material, at least one monocyclic or polycyclic aromatic compound which has at least 3 hydroxyl groups on the aromatic ring or, in a polycyclic aromatic compound, on at least one of the aromatic rings, and at least one partially cured water-dilutable A-stage phenol-formaldehyde resole resin, the coating composition being cured at elevated temperature. The coating composition is preferably such that when it is applied to a strand of glass fibres and cured at elevated temperature and the strand is subsequently encased in a block of ordinary Portland cement paste which is allowed to cure and subsequently kept for 28 days in water at 50‹C, said composition produces an improvement of at least 10% in the tensile strength of the strand as compared with that of a strand similarly tested but without application of the said composition. Suitable polyhydroxy aromatic compounds are pyrogallol, hydroxyhydroquinone, phloroglucinol, 2,4,6-trihydroxybenzaldehyde, 2,3,4- or 2,4,6- trihydroxyacetophenone, tetrahydroxy-p-quinone dihydrate, 2,3,4- or 2,4,6-trihydroxybenzoic acid, gallic acid, propyl gallate; products obtained by oxidation of the above compounds in alkaline solution e.g. ammonium oxidation salts of pyrogallol or gallic acid; barbituric acid, 1,2,4-trihydroxyanthraquinone, 2,4,6-trihydroxy benzophenone, tannic acid and naturally occurring vegetable tannins. In the Example an aqueous size comprising 5 or 10% weight of a phenol-HCHO resole resin, 5% weight of pyrogallol, and additionally a cationic wetting agent and gamma-aminopropyltriethoxysilane as coupling agent is applied to glass fibres, the coating is then dried and cured at elevated temperatures and the coated glass strands are then encased in a block of ordinary Portland cement paste and the cement cured and then aged in water at 50‹C.

Abstract: The present invention provides a carbon nitride-polyaniline nanocomposite and its preparation method as well as carbon nitride-polyaniline intumescent flame retardant coating and its preparation method, and relates to the flame retardant coating field. This invention aims to solve the problem of easy modification of epoxy resin and to form the epoxy resin and other materials' compounds whose performance may be superior to that of each other. However, there is mutual effect of very strong VDW force between layers of carbon nitride, which makes it very likely to cake and very hard to disperse in epoxy resin. The present invention applies cheap raw materials, and the process is easy to control. Carbon nitride-polyaniline intumescent flame retardant coating prepared with carbon nitride-polyaniline nano materials is of extraordinary fire retardance performance and environment-friendly.
